    Abstract Background/aims: Endoscopic biliary drainage is the gold standard treatment for cholangitis. The two methods of biliary drainage are endoscopic biliary stenting and nasobiliary drainage. A novel integrated outside biliary stent and nasobiliary drainage catheter system (UMIDAS NB stent; Olympus Medical Systems) was recently developed. In this study, we evaluated the efficacy of this stent in the treatment of cholangitis caused by common bile duct stones or distal bile duct strictures.
    Methods: We conducted a retrospective pilot study by examining the medical records of patients who required endoscopic biliary drainage for cholangitis due to common bile duct stones or distal bile duct strictures, and who were treated with a UMIDAS NB stent, between December 2021 and July 2022.
    Results: Records of 54 consecutive patients were reviewed. Technical and clinical success rates were 47/54 (87.0%) and 52/54 (96.3%), respectively. Adverse events were observed in 12 patients, with six patients experiencing pancreatitis as an adverse event, following endoscopic retrograde cholangiopancreatography (ERCP). Regarding late adverse events, five cases of biliary stent migration into the bile duct were observed. Disease-related death occurred in one patient.
    Conclusion: The outside-type UMIDAS NB stent is an efficacious new method for biliary drainage and can be applied to many indications.

    Abstract Backgrounds and objectives: Although pancreatic cancer (PC) has an extremely poor prognosis, the 5-year survival rate of patients with pancreatic high-grade precancerous lesion without invasive carcinoma (PHP) is favorable. PHP diagnosis and identification of patients requiring intervention are needed. We aimed to validate a modified PC detection scoring system regarding its detection ability for PHP and PC in the general population.
    Subjects and methods: We modified an existing PC detection scoring system that incorporates low-grade risk (LGR) factors (family history, presence of diabetes mellitus [DM] or worsening DM, heavy drinking, smoking, stomach symptoms, weight loss, and pancreatic enzyme) and high-grade risk (HGR) factors (new-onset DM, familial PC, jaundice, tumor biomarkers, chronic pancreatitis, intraductal papillary mucinous neoplasm, cysts, hereditary PC syndrome, and hereditary pancreatitis). Each factor was scored as one point; LGR score ≥3 points and/or HGR score ≥1 point (positive scores) were indicative of PC. The newly modified scoring system incorporated main pancreatic duct dilation as an HGR factor. The PHP diagnosis rate using this scoring system combined with EUS was prospectively analyzed.
    Results: Among 544 patients with positive scores, 10 had PHP. The diagnosis rates were 1.8% for PHP and 4.2% for invasive PC. Although the number of LGR and HGR factors tended to increase with PC progression, none of the individual factors were significantly different between patients with PHP and those without lesions.
    Conclusion: The newly modified scoring system evaluating multiple factors associated with PC could potentially identify patients with higher risk of PHP or PC.

    Abstract Polyunsaturated fatty acids (PUFAs) such as docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and arachidonic acid (ARA) are essential fatty acids for humans. Some microorganisms biosynthesize these PUFAs through PUFA synthases composed of four subunits with multiple catalytic domains. These PUFA synthases each create a specific PUFA without undesirable byproducts, even though the multiple catalytic domains in each large subunit are very similar. However, the detailed biosynthetic pathways and mechanisms for controlling final-product profiles are still obscure. In this study, the FabA-type dehydratase domain (DH

    Abstract Background/aims: Residual common bile duct (CBD) stones occasionally become symptomatic after stone removal with endoscopic retrograde cholangiopancreatography (ERCP) upon removal of the endoscopic biliary stent (EBS). An accurate evaluation of residual stones before stent removal is necessary. This study evaluated a new two-step check method using endoscopic ultrasound (EUS) for the detection of residual stones after ERCP stone removal.
    Methods: Fifty-six patients who underwent CBD stone removal and EBS placement were prospectively enrolled. Residual stones were evaluated by the check method. EBS was removed at the time of the check method or at a later time of residual stone removal. The primary outcome was to evaluate the efficacy of this check method.
    Results: Residual CBD stone/sludge was detected in 20 of 56 patients (35.7%; stones: 28.6%, sludge: 7.1%) by the check method and removed by the ERCP procedure at a later time. After stent and final stone removal, patients were followed for an average of 211 days; cholangitis recurred in only 1.8% of patients. There were no adverse events associated with the check method. Temporary EBS prevented the recurrence of cholangitis by residual stone and caused no adverse events in the pancreatobiliary tract until the two-step check method (median, 113 days; range, 17-232 days).
    Conclusion: The new check method may be ideal and feasible for EBS removal because recurrences are very rare when a clear CBD has been verified, and an additional ERCP procedure is also possibly avoided.
